Doing nothing has the imminent risk exchanges yet again misusing customer funds to implement a quick power down HF for them and there is also the risk that the economic nodes (i.e. exchanges) will then follow Justin's chain and not ours.
Yes exactly. This risk has always been there. If exchanges and Tron want to hardfork the protocol in a way the community does not support, let them do it. Let the exchanges initially support whatever chain they want to. The community gives the token value and in the longterm exchanges will support anything with value.
Hardforks are messy and confusing for users, but if an entity is determined to change the protocol against community wishes, a hardfork is an inevitability. Given that this hardfork would have Tron + Exchanges versus Community + Developers, I have little doubt the later would eventually come out on top.
